This derstood that the apparatus in all of its formsmay be effected in avariety of ways. As shown, consists, principally, ofa supporting base in the present case the plate 14 is slit at one plate,A, which for convenience will usually end, and its central portion isbent outward 0 be mounted upon legs or standards a, a bed or to form ahook, 4, which passes through an 90, rest, B, upon which the knife orother article opening in the end of the pad, while theother rests duringthe scouring operation, a head, 0, end of the plate is provided with asmall bolt, for applying the scouring material, which 5, which passesthrough a hole in the pad,and head is arranged to reciprocate over therest is provided at its outer end with a thumb-nut,

The base-plate A andthe pad 7 can be removed and another putin its legs a and the knife-restB may be made of place with little trouble. Any other suitable wood ormetal, as may be preferred, and the means may, however, be employed forsecur- 50 legs a will preferably be provided with rubing the pad inposition, if preferred. 10o

In order to secure the greatest ease and facility-in using theapparatus, as well as the best scouring effects, it is necessary thatthe.

plate 14, carrying the pad 7, should be capable of oscillating, so as toassume different angles with relation to the rest B to conform tovariations in the surface being acted on. It is also desirable that thehead Oshould be so held and guided in its reciprocations that it willnot only be moved in a straight line along the knife-blade or othersurface'being acted on, but will also be prevented from twisting orturning on its axis during its reciprocations. It is also desirable thatthe scouring-head 0 should be so held and guided that it can,whenidesired, be raised and turned back away from the rest B. As shown inFigs. 1 to 4, these several results are secured, as follows: The rod 15is connected between the plate 14 and handle 16 to a plate, 17, by apivoted joint, 28, which permits the whole head 0 to be oscillated in avertical plane at right angles to the rest B. The plate 17 is pivotallyconnected to the ends of a pair of horizontal parallel bars, 18, whichare pivotally connected at their opposite ends, as shown at 26, to aplate, 19, which in turn is hinged to a vertical yoke, 20, the ends otwhich are hinged to the base-plate A, as shown at 22. At a point aboutmidway of their length the bars 18, or one of them, are or is pivotallyconnected, as shown at 25, to one end of a horizontal bar, 21, theopposite end of which is pivotally connected, as shown at 27, to ahorizontal bar, 23, which is hinged to the base-plate A, as shown at 24,butis not capable of any horizontal movement. It will be observed thatthe parts are so proportioned that the distance from the pivots 26 tothe pivot 25 is just equal to the distance from the pivot 25 to thepivot 27. From the construction and arrangement of the parts justdescribed, it results that the head Ocan be oscillated or rocked, asshown by dotted lines in Fig. 2, so as to cause the plate 14 and pad 7to assume differentangles with relation to .the rest B, also that thehead 0, as it is reciprocated along the knife-blade or other article onthe rest B, is always caused to move in a straight line, and isprevented from twisting or turning on its own axis, as shown by dottedlines in Fig. 1, and also that the head 0 and its connections can bereadily turned upward away from the rest B, when desired, as shown bydotted lines in Fig. 2.

The manner of using the cleaning and scouring apparatus thus constructedis as followsi To supply the pad 7 with the scouring material, the coverportion 13 of the rest B is turned to one side, as shown by dotted linesin Fig. 1, so as to uncover the receptacle containing the scouringmaterial 12. The head 0 can then be moved into position over thereceptacle containing the scouring material, and the pad 7 pressed downonto the material, so as to take up a portion of the same. The scouringmaterial 12 may be any suitable paste or powder which is adapted forcleaning, polishing, or

scouring purposes. After the pad 7 has been supplied with the scouringmaterial, the cover portion 13 will be restored to its originalposition. The knifeblade or other article to be cleaned or scoured will,then be laid on the rest B, and the head 0 will be grasped by the handle16 and moved back and forth, so as to carry the pad 7 along the surfaceto be scoured. As the head Gis moved back and forth along the rest B,the parallel bars 18 will prevent it from twisting or turning upon itsaxis, so that the sides of the plate 14 and pad 7 will always bekeptparallel with the rest B, and the bars 23 21 and the hinged yoke 20will so guide the head that it will be caused to move in a straight linealong the rest. As the head 0 is moved back and forth along the rest, itcan, if necessary, be oscillated on the pivot 28, as shown by dottedlines in Fig. 2, so as to cause the pad 7 to take different posit-ionswith relation to the rest, and thus accommodate itself to the sur facebeing acted upon. The hinges 22 24 allow the head 0 to move up and downfreely, and thus accommodate itself to articles of varying thicknesses,and these hinges also permit the head and its connections to be turnedupward, entirely away from the rest B, when it is desired to do so, asshown by dotted lines in Fig. 2.

Although the structure illustrated in Figs. 1 to 4 embodies theinvention in what I regard as the best form, yet this structure may bemodified in many particulars without materially changing its modeof'operation, and it may be modified in many other particulars, and yetpreserve certain features of the invention. r

Some of the many modificationswhich may thus be made are illustrated inFigs. 5 to 11. The construction shown in Figs. 5 and 6 varies onlyslightly from that already described, the only difference being that theplate '19, to which the rear ends of the bars 18 are pivoted,

insteadof being hinged to a vertically-an to provide suflicient room forthe necessary movement of the plate or head 19. This constructionprovides for exactly the same movements of the head 0 as that firstdescribed, and

IIO

in some cases may be found equally or more desirable. It is also to beremarked that in either of the constructions already described,

instead of having both of the bars 18 extend fiom the plate 17 to theplate 19, one of the bars may extend only from the plate 17 to the pivot25; but in-such case a second bar, 21, will be provided, as indicated bybroken lines in Fig. 1. 7

Where the head 0 is arranged to oscillate,

as shown in Figs. 1 to 5, it will usually be the base-plate, as shown insaid figures. In

preferable to have the knife-rest B fixed to some cases, however, it maybe desirable to have the head 0 fixed in the plate 17, so that it willnot be capable of oscillating, and in such case the knife-rest B maybemounted on trunnions, as 29, which enter standards, as 30, rising fromthe base-plate, as shown in Figs. 7, 8, and 9. By this means theknife-rest is allowed to rock, as indicated by dotted lines in Fig. 9,so as to properly present the'article to the pad 7 to be acted on. Insome cases it may be desirable to have the knife-rest arranged in thismanner, even where the head C is pivoted, as shown in Figs. 1 to 5, andthis of course can readily be done.

In some cases, especially where the appa ratus is designed for someparticular class of work, it may not be necessary or desirable to haveeither the kniferest or the head 0 arranged to oscillate, and it is tobe understood, therefore, that this feature may be wholly omitted andyet preserve certain important features of the invention.

In some cases it may be preferred that the head 0, instead of beingprovided with the pad 7 for applying thescouring material, may beconstructed to carry a solid scouring ma terial, such as a small brick.In such case the solid scouring material may be secured to the underside of the plate 14 in any convenient 1nanner.- \Vhere a solid scouringmaterial is used, it will of course not be necessary to provide areceptacle in the knife rest B for the scouring material, and the restcan therefore in such case consist of asimplc solid block of woodormetal. \Vhere asolid scouring material is used, it will usually beprefer able that the knife-rest B should be arranged to oscillate, asalready described, and that the head 0 should be incapable ofoscillation. It will therefore in such case be preferable to have thehead 0 constructed in a manner somewhat different from that alreadydescribed. In such case also it will not be so important that the head 0and its connections should be capable of being raised or turned up awayfrom the rest B, and this feature may therefore be omitted.

In Figs. 7 and 8 aconstruction is illustrated which embodies themodifications just indicated. In this case the knife-rest B is a simpleblock of wood or metal,which is hung on trunnions 29, as beforedescribed. The head 0 consists of a vertical block, 40, to which theends ofthe bars 18 arepivoted the same as to the plate 17 in theconstruction before described.

The block 40 is provided upon its front side with a clamp, 3l,which isof suitable size and form to receive a brick, 32, of suitable solidscouring material, and is provided with a clamping-screw, 33, by whichthe brick is held in position. One of the bars 18 terminates at thepivot 25, as before described, and the other, instead of being pivotedto the plate 19, is provided with a stud, d, which passes through andmoves to and fro in a slot, e, in a bracket, 39, which is rigidlysecured to the base-plate A. The bar 23 is omitted, and

the bars 21there being two of these bars, as before described-arepivoted at their front ends to a fixed block, 35. The manner of usingthe apparatus when thus organized is substantially the same as alreadydescribed. The head 0 and its connections cannot, however, be turned upaway from the. kniferest. Where the brick 32 of securing material isused, the apparatus will preferably be provided with anabrading-surface, as 34, located at the end of the knife-rest, uponwhich the lower end of the brick can be rubbed to renew its surface whenit has become glazed by use. 1 By loosening the screw 33 the brick 32can be adjusted downward as it is worn away. It is to be remarked thatin this construction the bar 18, instead of being guided by the slot 6in the bracket 39,1nay be pivoted to one end of a laterally-extendingbar, 36, the

opposite end of which is pivoted to a stud rising from the base-plate A,as shown by dot-ted lines in Fig. 7. Such a bar, 36, will serve to guidethe bar 18 in substantially the same manner as the slot 6. )Vhen the bar36 is employed, the base-plateAwill of course have to be enlargedsomewhat, as indicated by the dotted lines. The head C, instead of beingof the form shown in Figs. 7 and 8, may, if preferred, be of the formshown in Figs. and 11. In this case the block 40 is of the L form, andthe clamp 31 is arranged to clamp the side instead of the edge of thebrick 32 against the block.

It will readily be understood that the form of scouring head shown inFigs. 1 to 5 may be used in connection with the form of holding andguiding bars shown in Figs. 7 and 8; or that the forms of head shown inFigs. 7, 8, 10, and 11 maybe used in connection with the form of holdingand guiding bars shown in Figs. 1 to 6.

The several ways of arranging the bars for holding and guiding thescouringhead which are shown and described are regarded as the best forthe purpose, because by these arrangements of the bars the head is notonly held and guided in a straight line along the knife-rest, but isprevented from turning or twisting on its axis. The former of theseresults, which is by far the most important, will be secured when onlyone of the bars 18 is employed, the second bar 18 being provided merelyfor the purpose of securing the second result. It is therefore manifestthat one of the bars 18 may be omitted and yet preserve the mostimportant feature of the invention.
